Methodology for ND9 “Code 9” charges
- The Anytime Demand is highest half-hour demand at any time between 1 April and 31 March, with a minimum chargeable demand of 150kVA.
- The Shoulder Demand is the average of the six highest daily half-hour demands from 0700-1000 and 1700-2130 from May to September with a minimum chargeable demand of 150kVA.
- Both the Anytime and Shoulder Demand Charges are charged in every month.
- The Reactive Penalty Charge is assessed on the basis of a 0.95 lagging power factor coincident with the highest half-hour demand each month.
Methodology for ND10 “Code 10” charges
- The ND10 plan is an alternative for ICP’s with half-hour metering where the ND9 plan is unsuitable.
- The Excess Reactive Charge is assessed on the basis of an average 0.95 power factor over an entire month.
Note: ND 9 and ND10 are only available at ICP’s with half-hour metering. Switches to or from ND9 and ND10 can only be made on the first day of a month.
